' Application filed ltovember a full, clear, and exact description of the V invention, suchas Wlll ena-ble others skilled in the art to which it'appertains to make and'use thesa'mei a this invention relates-to an attachment for -a printingpre ss and involves the provision of a device of this character for'imprinting numbers, dates or otherdata supplementary to the main body of matter printed on sheets by the press itself. a Heretofore printing sheets, for example, withzconsecutive numbers; the common practice has been to allow space in the printing form for the insertion of fa typographical numbering machine. Machines of this character are provided with means forautomatically advancing the number type in consecutive order as the main body of matteris being printed so that thesheets,

consisting of certificates, coupons and the like will be consecutively numbered as they are printed; This method of printing sheets with supplemental matter. of. the'character indicated has various disadvantages. In the first place the correct positioning of the machine in the printing'form :requires'that the most exact adjustments :be made in order not only that the numbers or otherma-tter will be accurately placed'on the 'sheet, but also that the type of the machine must be from the type of the ina'chiner'without affecting the printing of the typein the retype, various expedients must be resorted to to block out the plunger-sothat 'itrv'vill be prevented from printing; Frequently it; is

desired to print identifying matter such as numbers in dlfier'ent colors from :the main body of the"printed matter,'- andfagfurther obvious di advantage, therefore, in placing the numbering ma hine in" theform s thatit precisely type high-toobtain thefimpression'.

Such inking. means consist preferably of inking rollers carried by the attachment, one of the rollers being a vibrator roller. actuated by parts of; the attachment are mounted upon a swinging frame pivoted to a standard which is bolted on the frame of the press.

By connection with the operating lever of the press, the swinging frame may be advanced to printing position, or retracted to inoperative position when it is desired to Gil mg machines;

run the press without the attachment. In this specific example of the attachment the construction is adapted primarily for numbering work by means of a numbering machine held in the clamps carried on a reel constituting the rotary type-holder. In order that the operating plunger of the num bcring 7 machine will be prevented from printing, the inking roller of the attachment supplying ink to the type of the numbering machine is preferably a sectional form of roller, the sections composing which may be move-d so that ink will be applied to the type only ofthe machine and not the plunger.

The invention is illustrated in the accompanying drawings in the form of a numbering attachment in application, as example, to a cylinder press'of the type known as the 'Babcock press, and in the drawings Fig. 1 is a view in elevation of a portion of the printing press illustrating the numbering device attached thereto; t

A -1 Referring to the drawings in which like characters indicate corresponding parts throughout the several views, the attach- I ment constituting the invention is'supported on a frame 7 which in turn is bolted as M8 to theframe 9 of the press. Pivoted in bearings 10 is a frame 11 which carries the operating parts of the attachment. Bolted to the frame 11 as at 12 are bearings 13 in' which is journaleda shaft 14. Mounted screws 17 for. securing the reels in adjusted i 9 position along the shaft.

of eachof the reels is formed with tapering sides 18 providing retaining guideways for a plurality of clamps 19 slidably mounted upon each of the reels. The clamps 19 are made in two pieces having complemental tapering recesses fitting the tapering sides 18 of the periphery of the reel and forming a dovetail sliding connection. The two The periphery parts of the clamp 19 are held together by means of a bolt 20 and nuts 21 at each end thereof by which the parts of the clamp may forced together totighten the latter in adjusted position upon the reel. [The upper part of. each of the clamps 19 is cut away as at 22 to provide a recess for receiving the numbering machine which may be any of the known commercial numbering. 111361111168 in use.

various sizes are accommodated in the up- Numbering machines of per recess of the clampbyproviding liners such as 23, illustrated in detail in Fig. 6,

the liners being provided with pins 2 1 for fastening themin the apertured walls of the clamps forming the recess as illustrated in Fig. The clamps and numbering machines therein, disposed around the periphe cry of each of the reels, and the number of reels and their positions on the shaft 14 may be regulated to. meet the requirements of each specific printing job.

In View of the location of thenumbering machine above the type line 25 of the reciprocating bed 26 of the press, means are provided for inking the type of the numbering machines independently of the ink- 7 ing rollers 27 of the press. Such means consist of a series'of rollers 28, 29 and 30 j ournaled in bearings 31 bolted to the'frame 11. The rollers arccustom'arily three in number, the roller 28 taking ink from'the inkrecepta'cle being ofmetal, and the rollers 29 and 30being of composition material and transferring the ink from the metal v roller 28' to the type ofthe numbering machines. Like the intermediate vibrator roller of the system of rollers 27 inking the type of the printing form held in the reciprocating bed 26' of the press, the intermediate roller 29 of the attachment is arranged to be reciprocated back and forth-across the rollers 28 and 30 to spread the ink and produce an even distribution thereof on the type of'the numbering. machines; The vibrator -roller 'or intermediate roller 27 of the press is reciprocated laterally across the surfaces of'the remaining rollers by means I of an 'eccentric 32, the system of links 33 and the pin 34 riding ingrooved wheel 35 at the end ofthe rolleras' is comm'on. in

printingpressconstruction; For-the pur- =pose1of imparting a reciprocatory move- :ment to the intermediatespreader-roller 29 ,of the attachment, a link 36 is provided cated back and forth by means of the eocentric. 32 and link connections, the reciprocatory movement ofthis roller is communicated-to the roller129iof the attachment thus effecting a lateral movement of this roller across the: surfaces of the rol lers 28 and 30, and producing an even distr bution of the ink on the roller a'ndconseq'uently on the face of the type of the numbering machines. d

In the "position of the attachment illustrated in Figs. 1 and 2, theswinging frame.

machines will contact with the stock fed to the cylinder 40 of the press from the feeder 41. In order that the attachment.

may be retracted to inoperative position a link 42 is provided which is attached at one end thereof at 43 to the operating lever 44 of the press and pivoted at the other end thereof as at 45 to the frame 11. By operating the lever 44, therefore, the frame 11 and the parts of the attachment mounted thereon may be raised above the frame 7 and moved out of operative position.

The shaft 14 has at one end a gear 46 which is in mesh with the cylinder gear 47 of the press by which the shaft 14 is driven. The gearing is in the ratio of two revolutions of the shaft 14 to one revolution of the press cylinder when the attachment is used in conjunction with a ,press of the drum cylinder type, and in the ratio of one revolution of the shaft 14 to one of the press cylinder when the attachment is used on a type of press known as the two-revolution cylinder. p 7

It will be seen by an inspection of Fig. 5 that the numbering machine consists of a plurality of reels 48 carrying number type, the first of which series'of reels is operated by a plunger 49, the remaining reels being advanced as the numbers progress. In the plunger 49 on the stock is 1 avoided.
